$BTC (Bitcoin)

Bitcoin ($BTC) is the first and most well-known cryptocurrency, launched in 2009 by the mysterious Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network without the need for intermediaries like banks. Bitcoin uses blockchain technology to securely record transactions and prevent double-spending. With a fixed supply of 21 million coins, it is often referred to as "digital gold" due to its scarcity and store-of-value potential. BTC can be used for payments, trading, or holding as an investment. It has influenced the creation of thousands of altcoins and remains a dominant force in the world of digital finance.
